Detroit Auto Show Live 20: BMW M Roadster

M POWER FOR Z4--FINALLY
The roadster market is like the modeling world. Only the youngest and hottest bodies get the money. BMW's Z4 Roadster is a little like Christie Brinkley. She's still hot but, well, she's not quite what she used to be. Well, BMW has decided to give the Z4 the automotive equivalent of Botox. Which, just for the record, is much better than doing fitness equipment infomercials with Chuck Norris like our pal Christie. Underneath that long Z4 hood BMW shoehorned in the M3's fantastic 3.2-liter straight Six to create the new M Roadster and help it compete with Porsche's new Boxster. In this configuration, that engine makes 320 hp and comes with a six-speed manual (our choice) or a six-speed automatic. Expect to pay around $52,000 when the new M Roadster hits stores this summer.--Ben Stewart
